This textbook provides an introduction to general relativity for mathematics undergraduates or graduate physicists. After a review of Cartesian tensor notation and special relativity the concepts of Riemannian differential geometry are introducted. More emphasis is placed on an intuitive grasp of the subject and a calculational facility than on a rigorous mathematical exposition. General relativity is then presented as a relativistic theory of gravity reducing in the appropriate limits to Newtonian gravity or special relativity. The Schwarzchild solution is derived and the gravitational red-shift, time dilation and classic tests of general relativity are discussed. There is a brief account of gravitational collapse and black holes based on the extended Schwarzchild solution. Other vacuum solutions are described, motivated by their counterparts in linearised general relativity. The book ends with chapters on cosmological solutions to the field equations. There are exercises attached to each chapter, some of which extend the development given in the text.read more

The Physics of Cosmic Acceleration
TL;DR: The discovery that the cosmic expansion is accelerating has been followed by an intense theoretical and experimental response in physics and astronomy as discussed by the authors, which implies that our most basic not-basic not...

Black hole thermodynamical entropy
TL;DR: In this paper, a generalized Boltzmann-Gibbs (BG) entropy was introduced for the Schwarzschild black hole and the area law, which can solve the thermodynamic puzzle.

Geometry of stochastic state vector reduction
TL;DR: In this paper, the authors use stochastic differential geometry to give a systematic geometric formulation for such models of state vector collapse and show that the probability of collapse to a given eigenstate, from any particular initial state, is, in fact, given by the usual quantum mechanical probability.

A (giant) void is not mandatory to explain away dark energy with a Lemaître-Tolman model
TL;DR: In this article, the authors show that the current density profile does not exhibit a giant void, but rather a giant hump, which is not directly observable, since it is in a spacelike relation to a present observer.
